Introduction: Mediastinal masses are relatively uncommon and continue to be an interesting diagnostic and therapeutic challenge to thoracic surgeons. Although they tend to be more common in young and middle-aged adults, numerous types of mediastinal tumors and cysts affect people of all age groups. Epidemiologic survey of mediastinal tumors can get important information for physician and health experts. Materials and Methods: in this retrospective descriptive cross sectional study, documents of 109 patients with primary diagnosis of mediastinal tumor managed in the Razi Hospital between March 2006 and March 2012 were reviewed. 8 cases were excluded. Statistical analysis was done with SPSS (version 16).
Results: This study was carried out on 101 patients, the mean age was 35.84±1.71 years and 56.4% of them were male. The most common mediastinal tumors were Non-Hodgkin lymphoma (30.7%), Thymoma (13.8%) and Hodgkin lymphoma ( 12.9%) respectively. 78.2% of tumors was in the anterior mediastinum. the most common symptoms were Cough and dyspnea; open biopsy was the most diagnostic method; CXR and CT scan were the most common imaging studies. There were seen significant differences between type of tumor and location of them (P<0.001). In addition, no significant differences were seen between different location of tumor and age (P=0.4) and gender (P=0.82).
Conclusion: This study showed that mediastinal tumors were common in young male adults. Cough and dyspnea were the most common symptoms. In addition, lymphoma and Thymoma were the most common mediastinal tumors that were similar to previous studies.
